Hi, I have a Czech antenna that looks exactly like an A3S. It is probably a
clone. The problem is that this antenna is resonant about 200kHz down from
CW band edge ON ALL THREE BANDS (14, 21 and 28). I got this antenna second
hand.
I tried to shorten the elements as far as they go but it seems that the
effect on resonance is marginal at best.
Now, I realize that few, if any of you have any experience with the exact
model, but, given the resemblance with A3S mode, thought to ask for any
hint. Thanks in advance.
